Remarks

Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m. Superseded by parameter values derived from transformations to ITRF2020 (change in tX), see EPSG:10142.

Frequently Asked Questions

How do I convert ITRF91 to ITRF92 coordinates?

Use the coordinate transformation tool above to convert ITRF91 (EPSG:4913) to ITRF92 (EPSG:4914). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geocentric domain) method with 0.005m accuracy.

How do I transform ITRF91 to ITRF92 using Proj4js?

Use proj4.defs to define both EPSG:4913 and EPSG:4914, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the ITRF91 to ITRF92 transformation?

This transformation (EPSG:9023) has an accuracy of 0.005m using the Position Vector transformation (geocentric domain) method. Area of use: World.
